  • "Determine the ability of 129Xe MRI/MRS biomarker signatures to non-invasively monitor pulmonary vascular reverse remodeling induced by sotatercept in pulmonary arterial hypertension (PAH)."
Compensation
Not stated
  • Study-related exams and procedures are typically provided at no cost. This is how many trials work in general — confirm the details for this study with the study team.
  • Participants are monitored closely by the research team throughout the study.
  • Some participants may receive access to an investigational treatment, which is still being studied.
  • Your participation helps researchers learn whether this approach could help future patients.

About this study

Eligibility

Official eligibility criteria

Inclusion Criteria: 1. Outpatients of either gender, Age 18-75 2. Diagnosis of precapillary PH (right heart catheterization demonstrating hemodynamic criteria of a mean pulmonary artery pressure (mPAP) ≥ 20 mmHg, pulmonary vascular resistance ≥ 5 WU, pulmonary capillary wedge pressure ≤ 15 mmHg) in the setting of Group 1 (PAH) 3. Willing and giving informed consent and adhere to visit/protocol schedules (consent must be given before any study procedures are performed). 4. On a stable dose of background PAH therapy for \> 90 days prior to study enrollment 5. Women of childbearing potential must have a negative urine pregnancy test before MRI Exclusion Criteria: 1. Moderate to severe heart disease (LVEF \< 45%, Severe LV hypertrophy, Moderate to severe valvular disease) 2. Chronic thromboembolic disease 3. PH due to schistosomiasis 4. Active cancer 5. Sickle cell anemia 6. Prisoners and pregnant women will not be approached for the study 7. Conditions that will prohibit MRI scanning (metal in eye, claustrophobia, inability to lie supine) 8. Medical or psychological conditions which, in the opinion of the investigator, might create undue risk to the participant or interfere with the participant's ability to comply with the protocol requirements
